Considerations

The information in this section is intended as a guideline only; there may be site-specific
requirements and other factors that will require individual attention, such as jurisdictional codes
and construction covenants.

4.1 Site

Selection

The supporting structure must be designed to support a fully configured enclosure. This will require a concrete
slab and any existing structures to be properly reinforced to support the floor loading. In addition, the mounting
site must be designed and installed in accordance with local building practices and codes.

Site consideration should include the following:

• Areas that may receive hot air exhaust from neighboring buildings or structures should be avoided.

• Any areas with architectural controls or environmental restrictions should be known.

• Areas prone to flooding should be avoided.

• A proper grounding system.

The site must be planned so that the enclosure will receive good airflow. If possible, in areas of extreme heat, it is
best to position the enclosure so that it will be shaded from the afternoon sun. If no shade is available, a factory
installed fan kit is highly recommended. In areas of prevailing winds, it is best that the enclosure be located so
that the sides of the cabinet face the winds instead of the doors. This will greatly reduce the buildup of sand or
snow against the enclosure’s air vents.

In areas of potential flooding, the geographical site and concrete pad must be located above the 100-year flood
plain.

The enclosure must be placed where it will be free of obstructions, allowing easy access to the doors for service
or equipment access. For ventilation and maintenance, allow a minimum space of 36 inches in the front and 36
inches in the rear, between the enclosure and other solid structures.

Place the enclosure well away from sources of forced water, such as underground sprinkler systems and direct
roadway splash.

The concrete pad drawing provided in this manual contains all of the required mounting details, including
electrical service and cable plant entrances. For ease of installation, lightweight polymer concrete pads are
available.

The vapor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar paper) must initially extend
at least 6" in all directions around the perimeter of the enclosure and be trimmed closer to the enclosure.

Contact local utilities, local building maintenance departments or cable/piping locator services to ensure that
install does not interfere with existing cables or piping.

4.2 Enclosure

Protection

Argus Technologies Ltd. cannot anticipate all of the ways a vehicle may potentially threaten an installed system or
the specific type of protection that is appropriate for a particular location. The determination of the threat to the
equipment and the means of protection are the responsibility of the end user of the equipment and the authority
having jurisdiction. The numbers of Bollard posts (or other protection devices) depend upon equipment locations,
site surveys, traffic patterns and local codes. Do not install enclosure within ten feet of a water sprinkler to prevent
water from entering enclosure.

4.3 Enclosure

Grounding

In order to provide a ready, reliable source of backup power it is necessary to establish a grounding system that
not only provides for the safety of the service personnel responsible for its operation and maintenance, but also
facilitates the proper operation and protection of the equipment within the network. Such a grounding system will
provide protection with respect to operator safety, system communication, and equipment protection.
